8. ADJUSTMENT PROCEDURE 



Caution: 



This unit has been precisely adjusted at the factory before shipment. Therefore, absolutely do not turn any 
variable resistors other than those required for servicing. Furthermore, please allow thirty minutes of warm-up 
time after turning on the power before beginning check or adjustment. Please refer to the separate VR location 
chart. 




Cs 



Normal setting 



1. POWER SUPPLY adjustment (KLM-376). 
Connect DVM to KLM-356; GND is J12. 

1) -15V: Check J11 with DVM and confirm -15V 
(±0.01V). 

Adjust KLM-376 VR-3 if necessary. 

2) +15V: Check J40 with DVM and confirm +15V 

(±0.5V). 

3) +5V: Check left side of R54 (J39) with DVM and 
confirm +5V (±0.02V). Adjust KLM-376 VR-2 if 
necessary. 

2. KEY ASSIGNER adjustment (KLM-356). 

1 ) Assignor slope. 

CV1 output: Short the TUNE POINT; connect 
DVM to right side of KLM-356 R8 (GND is J12); 
change TRANSPOSE SW position in the order UP 
-*■ DOWN -»■ NORMAL and adjust to obtain the 
values shown in the chart.

3. PITCH adjustment (stretch tuning) (KLM-354). 

1) OFFSET adjustment 

Check KLM-398 lead wire connection points with 
DVM and confirm that each VCO offset voltage is 
±0.1mV. Adjust the KLM-398 VR if necessary.. 

Color code: 

VCO 1 — Red 
VCO 2 — Yellow 
VCO 3 ■+ Blue 
VCO 4-* Gray

VCA LEVEL adjustment (KLM-355). 

Connect oscilloscope (DC 0.5V, 1msec.) to SIG OUT 

or PHONE OUT. Use settings listed below. 

Settings: VCO-4 LEVEL ... 10 (VC01, 2, 3 

are at 0.) 

WAVEFORM A 

OCTAVE 16' 

Play C3 and confirm 1.5Vp-p. Adjust VCA GAIN 
VR10 if necessary. 
5. NOISE check. 

Set CUTOFF to 10, RESONANCE to f and VCOI, 

2, 3, 4 to 0. 

Set NOISE LEVEL at 10 and confirm 3.0~5.0Vp-p. 

After check, turn NOISE LEVEL back to 0. 

VCF check and adjustment. 

1) OFFSET adjustment. 
Set RESONANCE to 0, CUTOFF to 5. 

Use DVM to check both sides of R10. Adjust 

VR-19 to obtain 0.000V ±10mV. 

2) VCF LEVEL, Fc adjustment 
Set VC04 to 0, RESONANCE to 10, EG INT to 0, 
CUTOFF to 10. 
Use oscilloscope at DC2V, 0.1msec. 

Put any single key into HOLD. Confirm cycle T=* 
140/isec. and oscillation level is within 7Vp-p — 
11Vp-p (figure 1).

If necessary, adjust VR18 for Fc. If oscillation 
level is off, adjust VR3 to obtain 20Vp-p at both 
sides of KLM-355 R10 (with CUTOFF at 10 and 
RESOat 10). 

Confirm that oscillation begins when RESO- 
NANCE is turned up to 7 or above. 



7. RESONANCE VCA check and adjustment. 

Settings: Oscilloscope DC 0.5V, 1msec.

If indication is less than 1Vp-p when RESONANCE is 
at 5, then set VCO 1, 2, 3, and 4 LEVEL to 0, 
CUTOFF to 5, and RESONANCE to 10. Then adjust 

KLM-355 VR4 to obtain 60mVp-p across both sides 

of KLM-355 R44. 

VCF EG check. 

Set oscilloscope to DC 2V, 1msec, VCO LEVEL to 

10, HOLD to OFF, VCA EG A to 0, D to 0, S to 10, 

and R to 10. Then confirm changes in oscillation 

frequency as listed below.

TRACK to 10, HOLD to ON. Play C3 and turn 
CUTOFF to obtain about 4cm (250Hz), then play C4 
and confirm 1.1cm ±0.3cm (1250Hz~414Hz) as in

11. Wheel check and adjustment 

EFFECT SW, WHEEL SW pitch deviation adjust- 
ment 

Set all VCO OCTAVE selectors to 16', WAVE- 
FORM to , A # 4 key on HOLD. Connect WT-12 
(METER, OCT M, A # ) to SIG OUT and adjust to 

obtain cent reading. 

1) With VC01 LEVEL at 10, EFFECT MODE SW 
at SYNC, SINGLE, switch EFFECT SW ON and 
OFF and confirm WT-12 meter indication change of 

within 

2) With VCOI LEVEL at 10 and EFFECT SW off, 
change BEND SW between VC01/SLAVE, PITCH, 
and VCF positions and confirm ±1cent WT-12 
reading. Adjust KLM-353 VR-4 if necessary. 

3) With the same settings as 2) above, change MG 
switch position and confirm same ±1 cent reading. 
Adjust KLM-353 VR-5 if necessary. 

After check, turn VCO 1 LEVEL back to , 

4) VC02 LEVEL to 10, turn TUNE knob to obtain 

Ocent 

Set EFFECT MODE SW to X-MOD, SINGLE, 

X-MOD INT to 0, then turn EFFECT SW ON and 
OFF and check amount of change in tuner indi- 
cation. 

* 

5) Perform step 4) for VC03 and VC04 in the same 
way. 

6) Select VCO exhibiting the greatest variation and 
adjust VR-15 (KLM-354) to minimize change when 
EFFECT SW is turned on and off. 



Due to circuit modification, please make adjustment 
according to following measures on the MP-4 after MAY 
production. 

[KLM-355] 

1 NOISE GAIN check and adjustment. 
Set VC01 , 2, 3, 4 to
